Product Description
Pacific S-20 20" Pad-Assist Walk-Behind Auto Scrubber
A compact 20-inch disk scrubber with 11-gallon solution capacity, 13-gallon recovery capacity, automatic brush installation and removal, and multiple battery and charger configurations.
The Pacific S-20 Pad-Assist is designed for daily scrubbing, deep cleaning, finish removal, entryways, classrooms, checkout aisles, restrooms, and other small-to-medium commercial areas. Its pad-assist drive system uses the rotation of the brush or pad to help move the machine forward, creating a simple, economical scrubber without a powered traction motor.
The S-20 combines a 20-inch cleaning path, 230 RPM disk head, adjustable 60 or 90 lb pad pressure, a 30-inch squeegee, and full-access recovery tank. Four configurations allow facilities to purchase a complete wet-battery package, supply approved batteries and charging equipment separately, or select the international configuration when applicable.
